Any way to configure a javascript/html war with deployment-time
properties?
I'm using TomEE, but I think this question is Tomcat-specific, if there's any solution at all.
I have a WAR that is a "pure" webapp, with only javascript, css, and html. The javascript connects to a REST service at a defined host:port. The host:port is currently hardcoded in a javascript variable.
I really need to be able to configure this host:port at deployment time. I know how to do this sort of thing with Java apps, but I'm at a loss to see how to do this conveniently for a non-Java war.
How can I rearrange this solution so that I can change the host:port the WAR uses at deployment time?

If your content is non-dynamic, then it's .. non-dynamic. There is no
problem returning a dynamically-built javascript source file if you'd
like.
You have a lot of choices for how to dynamically-build a source file
like that, but if you were to use JSP, it could look something like this
:
// This is my "pure" webapp, with only javascript, css, and html
var serviceBaseURL = '<%=
request.getServletContext().getAttribute("baseURL") %>';
// Here is the rest of your application.
Hope that helps,
